The Exynos System-on-Chips have ~7 distinctive I2C IO ports (exact
number depends on chip). However some integrated circuits on board, also
using I2C protocol for communication, can be connected to the SoC by
other GPIO. Enabling the I2C GPIO driver allows using such additional
integrated circuits.
An example of such chip using I2C and connected over GPIO to SoC is
Maxim 77693 MUIC on Trats2 board. The regulator driver of Maxim
77693 offers charger and safeout LDO (necessary for USB OTG).

Removed outdated configs. Enabled most of the configs used on latest
Exynos based platforms. This will provide a reference for users trying
to verify and test various features on Exynos based platforms and also
help in detecting breakages by widening the build coverage.

High speed I2C is used on Exynos5 based SoCs. Enable it.
The MMC partition for Root filesystem cannot be mounted
without this enabling HS-I2C and regulators on many boards
are connected HS-I2C bus so the regulators don't come by
default without this.
Actually, we are not able to get arndale-octa board to boot
and mount an MMC partition without this change.

Merge tag 'v3.13-rc5' into next/boards
Need a newer base version to get a regulator fix for Samsung platforms that
they enable building in a defconfig.
Linux 3.13-rc5
Current CONFIG_NR_CPUS value (2) is too small for:
- EXYNOS4412 (4 cores)
- EXYNOS5440 (4 cores)
- EXYNOS5410 (8 cores)
- EXYNOS5420 (8 cores)
Set CONFIG_NR_CPUS to 8 so it is correct for all currently
supported SoCs.

Many of the boards use GPIO-mapped buttons for generic input.
For Arndale board, these buttons also serve as wakeup source.
And the issues reported in commit 522ccdb6fd ("ARM: dts:
Disable the RTC by default on exynos5") are no longer reproduced
on EXYNOS5250 based systems. Hence it would be better to re-enable
RTC support for EXYNOS5250.

This turns on a number of configs that are useful on the Chromebook, but also
good to have on in general:
* USB host and MMC drivers(!)
* I2C GPIO arbitration driver
* CYAPA trackpad driver
* simplefb
* CROS EC and keyboard drivers
* S5M8767 driver
* MAX77686 drivers
* MAX8997 driver
* DEVTMPFS + mount
* DM_CRYPT (as module)
* CRYPTOLOOP
* HIGHMEM
* PRINTK timestamps
This also turns off DEBUG_LL, and switches the hardcoded Samsung lowlevel
uart to uart 3 (which is only used to show the "uncompressing kernel"
message at boot, it seems).

This enables the new EXYNOS5 platforms in the defconfig, and enables DT
support on EXYNOS4.
Other options enabled: USB host, EXT3/4, regulators and tps65090,
networking and a few of the common usb ethernet adapters as well as the
smsc911x controller used on some boards.
I enabled EFI_PARTITION, since it's used on some filesystem images I'm
using. I didn't see a need to keep Solaris and BSD partition format
still enabled.
Finally, framebuffer console, logo and fonts were enabled.
Note that enabling some of these options introduces build coverage
previously missing, thus introducing a few build errors and warnings
for which fixes have been sent out already.
